Can some one tell me what is : in java

Question

Array

Answer 1

It is called foreach loop when you used it on for loops like:
String[] arr= {"python" , "Ruby", "Java", "c#"} ;
for(string x:arr) {
System.out.println(x);
}
Output:
python
Ruby
Java
c#

Which is equivalent to

for(int i=0;i<=arr.length-1;i++){
System.out.print(arr[i]);
}

and it is also equivalent to
//Java 8
arr.ForEach(System.out::println);
